continua and interrupta are both Mayr species, from adjacent pages in the same 1887 publication. The type localities are Santa Catarina, Brazil for continua, and "Patr. ? M. Dresd./Sudamerika" for interrupta. In Brown's revision the two species are differentiated mainly by size. Lattke (1995) distinguishes continua and interrupta by the presence or absence of a metacoxal tooth. Costa Rica material that I identify as various forms within this complex are variable in this character, and I cannot easily ally them with one or the other. I currently recognize four forms, which show patterns of broad sympatry across Costa Rica. These "forms" are based on relatively few collections, and their further definition will require additional collections. The forms are:

I have one Venezuelan specimen in this group, examined by Lattke and identified as continua (but no Lattke ID label). It has a metacoxal tooth that is more developed than any Costa Rican material, is small (like JTL-002) and ferrugineus, but otherwise is a small, light-colored version of JTL-001 (costae on the pleural regions, similar ventral petiolar process). I have a Colombian specimen which was identified by Lattke as interrupta. It is nearly identical to Costa Rican JTL-002, with the exception of a well-developed metacoxal tooth, like the Venezuelan specimen.

Gnamptogenys interrupta is encountered infrequently, as occasional workers in berlese or Winkler samples of litter from the forest floor.
